Answer:
<h2>4000
</h2>
Explanation:
The temperature of 0.1 kg of liquid rises from 25°C to 50°C in 300 sec. Energy of 13,600 J was supplied during this time. Appartus was losing energy at the rate of 12 J/sec.
Let us assume the Specific heat capacity as 
.
As there is no state change from liquid to gas, only Specific heat capacity is involved. Also, work done is approximately zero because volume does not change much. So,
Energy gained = Energy required to rise the temperature
Energy gained by liquid = 
∴ Specific heat capacity of liquid = 4000 
Answer:
T = 25 N
Explanation:
The question says that "A 25 n block is suspended by a wire from the ceiling vitamin the tension that appears in the wire
?"
Weight of the block, W = 25 N
Weight of a body acts in downward direction and tension acts in upward direction. It would mean that,
Tension = weight of the block
T = mg
T = 25 N
Hence, the tension in the wire is 25 N.
Charging a balloon and rubbing it on wool is an example of static electricity.

Answer: Cells require a constant input of energy to maintain their high level of organization.
Explanation:
According to the second principle of thermodynamics:
<em>"The amount of entropy in the universe tends to increase over time
".</em>
That is, in any cyclic process, entropy will increase, or remain the same.
So, in this context, entropy is a thermodynamic quantity defined as a criterion to predict the evolution or transformation of thermodynamic systems. In addition, it is <u>used to measure the degree of organization of a system. </u>
<u />
In other words: Entropy is the measure of the disorder of a system and is a function of state.
Now, in the specific case of cells, in order to maintain their high level of organization, which goes against the natural tendency to disorder, a constant input of energy is necessary to maintain that level.
